Kristen Stewart hit the red carpet to support beau Robert Pattinson at the premiere of his new film 'Cosmopolis' at the Cannes Film Festival tonight, however the incredibly private couple chose not walk in together with Kristen cuddling up to Tom Sturridge instead.
The 22 year-old inexplicably chose to put her arm around her 'On The Road' co-star and best friend of Robert, leaving her boyfriend to walk up the red carpet all on his lonesome.
She was wearing a scene-stealing scarlet gown, with sexy lace side panels and deep plunging neckline, which was an altogether much more racy and grownup look for the 'Snow White And The Huntsman' star.
Although Robert and Kristen spent the majority of the evening at opposite ends of the red carpet to each other, earlier in the week the PDA-shy couple were spotted kissing and cuddling up to each other at an exclusive party, which was very out of character for the 'Twilight' pair.
What do you think of Kristen's racy look at Robert's premiere?
